MTM-UAS

MTM-UAS is known as a 3rd level MTM system and was developed between 1976 and 1978 by a consortium of the German, Swiss and Austrian MTM Associations. The system was specifically developed for small batch production where speed of analysis has priority over methods and operational detail.

The data was developed having in mind the following objectives -

High analysis speed

Reproducibility of working methods

Sufficient accuracy for standard operations

Universal Application

The system requires the following production characteristics -

Similarity of tasks

Standard work places

Good organisation of the work

Availability of good detailed work-specifications

Qualified workers, trained and motivated

The data was derived from MTM-1 analyses from films of typical batch production operations -

UAS level 1 (Basic Operations)

Consists of seven activities

Get and Place

Place

Handle Tool

Operate

Motion Cycles

Body Motions

Visual Controls

The data Card shows a total of 77 unique codes, whose values range from 5 to 160 TMU (0.15 to 4.8 secs).The accuracy of MTM-UAS, compared to MTM-1, has never been officially defined but generally it is claimed not to be suitable for non-repetitive cycles of less than 1.0 minute (2,000 TMU) but again as with MTM-2 it has been used successfully for shorter non-repetitive cycles.
